Q: I just joined a new parish, and the sign of peace seems rather brief. In my previous parishes the pastor left the sanctuary to greet the people. Sometimes they even passed out name tags so people could meet one another.

A: Your new parish is following proper procedures. Go here https://www.vatican.va/roman_curia/congregations/ccdds/documents/rc_con_ccdds_doc_20040423_ redemptionis-sacramentum_en.html and scroll to numbers 71 and 72.
In practice, exceptions are made in some ethnic communities.
